Final answer:
More than half of the Earth's freshwater is trapped in glaciers and ice caps.
Step-by-step explanation:
The correct answer is A) Glaciers and ice caps. According to the given information, more than half of the Earth's freshwater is trapped in glaciers and ice caps. Glaciers are large masses of ice that form over many years from compacted layers of snow in areas where more snow falls than melts. Ice caps, on the other hand, are smaller than glaciers and cover less area.
